During the forty-five years the Buddha taught, he granted thousands of sutra teachings to his disciples. Other teachings, directly inspired by the blessing of the Buddha and spoken by the great bodhisattvas, are also considered sutras. The most famous example of such a sutra is the Heart Sutra, which is recited by the bodhisattva Avalokiteshvara. Sutras spoken through mandate are those which the Buddha instructed his followers to compile from the teachings they had heard.[1]
